IMPROVEMENT IN WKINDOW-SHADES.

Specication forming part of Letters Patent No. 205,468, dated May 7,1878; application filed February 11, 1878.

To all whom it may concern:

Be it known that I, ATLRE W. LANE, of Philadelphia, Pennsylvania, haveinvented a new and useful Improvement in Window- Shades, of which thefollowing :is a specification:

The object of my invention is to so construct a stiffening-strip for thelower end of a windowshade, and to so combine it'withsaid shade that thelatter will be strengthened and the accidental tearing of the sameprevented. This object I attain in the following manner, reference beinghad to theaccompanying drawin g, in which- Figure l is a sectionalv viewof the lower end of a window-shade, showing the ordinary method ofsecuring the stiffening-strip thereto; and Figs. 2, 3, and 4, viewsillustrating my improvement.

The ordinary method of securing a stiffenf ing-strip to the lower end ofa window-shade, as shown in Fig. l, consists in forming a loop at thebottom of the shade by turning up the lower end and stitching it to thebody at x, the strip A being slipped longitudinally into the loop thusformed. The objection to this plan is that the stitches weaken thebrittle cloth of which shades are generally composed, and render thelatter liable to tear on the line of stitches when any unequal strain isexerted upon the strip A. To overcome this objection I use two strips, Band D, and secure the lower end of the shade between these strips, whichare held together in the center by means of the screw by which the knoba is held, while the ends are secured by caps b, preferably of metal,which embrace said ends and are held in position thereon by means ofscrews d, these caps serving also as an ornamental finish for the endsof the strips.

The strip Bfhas a dovetailed projection, and

lthe strip D a dovetailed groove, so that when the stripsare adapted toeach other and to the shade, as shown in Figs. 2 and 4, it is impossibleto withdraw the shade vertically. Y

By the above-described means of constructing and securing thestil'ening-strip the lower end of the shade is strengthened, and theobjection to the usual method of fastening entirelyT overcome, while,owing to the fact that the, weight is evenly distributed'on both sidesof the shade, the latter must hang perfectly straight. By the use of thestrips B and D, facilities Vare also afforded for the ready and secureattachment of the fringe to the bottom ofthe shade.

I claim as my invention- The combination of the shade and the strips Band D with the caps b, adapteohto the ends of the strips, substantiallyas described, and held in position thereon by means of transverse screwsd, as set forth.

In testimony whereof I have signed myname to this specification in thepresence of two subscribing witnesses.
